"The Cooler Master Tempest GP27U leaves little to complain about. It delivers a stunning picture with high contrast, brightness, and vivid color. Professional-grade video processing means a superlative gaming experience. And it’s a little less expensive than the competition."

"Gaming and HDR are the two target uses for this screen, and it does generally very well in both. For gaming there are good response times, a single overdrive mode experience for VRR, super low input lag and solid support for latest gen consoles too. The moderately high 160Hz refresh rate provides good motion clarity, and is a nice combination with the high 4K resolution that provides a sharp and crisp image."
